Bing change in eoRealBounds: it is now deriving from eoPersistent.

Browse source 
More important, the eoRealVectorBounds, vectorized version (a vector<eoRealBounds *>
has also become an eoPersistent object and now derives from an eoRealBaseVectorBounds
class.
A useful consequence (and actual motivatino) was to be able to have soem
eoValueParam<eoRealVectorBounds> with all possibilities for input
(see doc for Lesson4 in the tutorial for the syntax).
